Pass enums in angular2 view templates
Create an Enum:
enum ACTIVE_OPTIONS { HOME = 0, USERS = 1, PLAYERS = 2}Create a component, be sure your enum list will have the typeof:
export class AppComponent { ACTIVE_OPTIONS = ACTIVE_OPTIONS; active: ACTIVE_OPTIONS;}Create a template:
<li [ngClass]="{ 'active': active === ACTIVE_OPTIONS.HOME }"> <a routerLink="/in"> <i class="fa fa-fw fa-dashboard"></i> Home </a></li>
Create a property for your enum on the parent component to your component class and assign the enum to it, then reference that property in your template.
export class Parent { public dropdownTypes = DropdownType; }export class Dropdown { @Input() public set dropdownType(value: any) { console.log(value); };}This allows you to enumerate the enum as expected in your template.
<div class="Dropdown" [dropdownType]="dropdownTypes.instrument"></div>
If you want get Enum name :
export enum Gender { Man = 1, Woman = 2 }then in component file
public gender: typeof Gender = Gender;in template
<input [value]="gender.Man" />
